NEW FPS! NEED HELP? [closed]

Hey everyone i am creating a fps but i have little knowledge of everything

can someone explain to be how to make them? I know that it will be very hard but an example would be fine like can you use... What im trying to make is a first person shooter like phantom forces with reloading animations shooting animations aiming animations but its confusing and in the game you can change your primary, secondary! -------------MENU SETUP FOR THE GAME!---------------------- http://prntscr.com/7flshr ------------MENU SETUP FOR THE GAME!------------------------

mouse = game.Players.LocalPlayer:GetMouse()

mouse.KeyDown:connect(function(key)
    if key:byte() == KEY YOU WANT then
        WHAT YOU WANT TO HAPPEN
    end
end 

this script is very old and roblox had alot of updates and i dont know how to work it anymore. but works fine (AS IN VERY NOT SMOOTH!)~~~~~~~~~~~~~~~~~

THIS IS MY OLDER FPS SCRIPT! I NEED HELP ANYONE WANT TO HELP ME?---------------------------------------------

framework = workspace['framework'] resources = game.Lighting.resources

local settings = { right_cf = CFrame.new(-1, 1, -0.2) * CFrame.Angles(math.rad(-3), math.rad(-1), math.rad(0)); left_cf = CFrame.new(0.4, 1.2, .8) * CFrame.Angles(math.rad(-12), math.rad(30), math.rad(0));

ammo = 30;
max_ammo = 120;

}

local player = game.Players.LocalPlayer local character = player.Character local camera = workspace.CurrentCamera local mouse = player:GetMouse()

local hud = player.PlayerGui.HUD

------------------THAT IS ALL I WILL GIVE OF MY SCRIPT!-------------
